Laser engraving machine, there are three main components:
1. Hanging laser head within the laser generation system, mainly to provide laser pulse power. Through the laser head to produce laser light source. Generally, the material to produce laser light is mainly gas, solid and semiconductor. According to different processing objects. Different laser sources are used.
2. Motion servo system, mainly for the formation of text and patterns, according to the processing requirements, to provide the appropriate movement.
3. Workpiece mounting and positioning device.
Laser engraving, also known as laser engraving, is a surface treatment process with optical principles, is through the light energy of the laser beam leads to chemical and physical changes in the surface material and engraved traces, or through the light energy to burn off part of the material, showing the required etching of the graphics, text;
For example, I want to make a keyboard, he has words on it, the words have a blue, green, red and gray, and the key body is White, laser engraving,
Mobile phones and electronic dictionaries are used on the keys, a little simpler to say it is this way:
1, first spray oil, blue, green, red, gray words spray the corresponding color, pay attention not to spray to the other keys, so that it looks like the blue keys, green keys, etc. keys,
2, and then the whole of a layer of white spray, so that is a whole piece of white keyboard! At this point you can laser engraving, the use of laser technology and ID out of the key map made of film, carve off the top white oil, such as processing letter "A", carve off the strokes on the white, then under the blue or green on the exposure, so that the shape of a variety of colors of the letters of the alphabet keys
At the same time, if you want to translucent, it is with PC or PMMA, spray a layer of oil, carve off the part of the lettering, then below the light will come through. If there is light, it will come through, but then we have to consider a variety of oil adhesion properties, do not oil sprayed on a scratch off, it can be too embarrassing!
